Answer to Question 1
Nearly 795 million liters (210 million gallons) of oil contaminated the Gulf of Mexico. Scientists estimate that BP removed about a quarter of the oil, most of it recovered directly from the well, burned at sea, or skimmed by boats. Another quarter of the oil evaporated or dissolved into scattered molecules. And a third quarter was either naturally dispersed in the water as small droplets or chemically dispersed. But the last quarter hasn't been fully accounted for; this oil is called residual oil. Some scientists suggest that the majority of it formed slicks or sheens on the water, washed onto local beaches and marshes, and accumulated as tar balls on the sea floor. other scientists suggest that some oil never made it to the surface; instead, the oil formed diffuse plumes more than 1000 meters (3300 feet) below the surface and likely dispersed into the ocean, was biodegraded by microbes, or sunk to the sea floor as tar mats. Even years later, it's still not clear what happened to the missing oil.
